MEANS FOR TRANSFERRING THE MATRICES; FROM THE FIRST ELEVATOR TO SECOND ELEVATOR OF A MATRIX-COMPOSING AND LINE-GASTING MACHINE.

Application filed March 15, 1827, Serial No. 175,451, and in Germany October 26, 1928.

In a concurrent application for Letters Patent there is described an arrangement for transferring the matrices from the first elevator of a matrix composing and line casting machine to the lifter bar of the distributor, wherein a yielding resistant is adapted to bear against the foremostof the matrices to be transferred and effects the erection of any of the matrices'of the line which may be hanging slantwise, prior to their transfer to the lifter bar.

The arrangement according to the present invention is distinguished from that above referred to, in that it is of extremely simple construction and is so devised that even in the event of it being unintentionally moved, it will not at any ime occupy a position in which it will interfere with the nor- I mal working of the machine.

The drawings illustrate by way of example one constructional form of the inven tion as applied to a machine such as that known under the trade mark Linotype.

In these drawings Figure 1 is a diagrammatic front elevation showing the pertinent parts of the machine;

Figure 2 is a view similar to Figure 1 with the parts in different positions;

Figure 3 is a side elevation of Figure 2, and

Figure 4 shows two thick matrices in the first elevator, one in incorrect position and the other in correct position.

As is well known, in machines such as those above particularized, the lines of matrices 1 after the casting operations, are brought by the first elevator 2 into their highest position as illustrated in Figure 1 in order to admit of their being transferred, as shown in Figure 2, to the lifter bar 4 of. the second elevator. It may happen that the line contains thick matrices such as those shown in Figure 1 whose upper ears 6, by which they are suspended in the first elevator 2, are located at one side of the matrix whilst the toothed combinations 7 are located upon the opposite side. As the line. is slack through the slackening of the space-bands, during the ascent of the first elevator 2, the thick matrices will be suspended at aslant as is that shown at the left of Figure 4:, so that when the line is afterwards moved rightward, the combinations 7 are too low to engage with the teeth of the lifter bar 4:.

For the purpose of straightening or erecting the matrices according to the present invention, a roller 23 is pivotally mounted on one arm of alever'2 t, on whose second arm is similarly carried a further roller 23 The lever 24 is fast upon a stub shaft 25 which is journalled in the intermediate channel casting 3 and on which is also rigidly secured a disc 26 which is provided with two diametrically opposed peripheral I notches 27, 28. A roller 29 which is pivotally mounted upon a swinging arm 30 is adapted to engage with the said notches, under the influence .of a tension spring 31, after the manner of a spring detent.

The operation of the arrangement is as follows When the ascending line of matrices 1 reaches the position in which it is shown in Figure 1, its foremost matrix, as shown in Figure 4, contacts with the roller 23 which. by the engagement of the detent roller 29 in the notch 27, under the influence of the spring 31, is held in the position illustrated. 80 When the line of matrices is moved rightward, the lever 24 together with the disc 26, is turned clockwise, the said parts reaching the position shown in Figure 2, in which the roller 29 is moved out of the notch 27 and bears on the periphery of the disc 26. If the first elevator 2 now descends, it will come into contact with the roller 23 and thereby restore the device to the original position in which it is shown in Figure 1..

Through the symmetrical form of the lever 24 and disc 26 no trouble could arise from any unintentional rotation of the lever 2-1, and in every instance the upwardly or downwardly moving first elevator 2 will ensure the arrangement returning to the correct operative position, wherein either one or other of the rollers 23, 28, and also one or other of the notches 27, 28, will be brought into operative position.

The abutment 12 which is provided in the intermediate channel casting 3 fulfils the function of an extension of the matrix guide rail of the first elevator 2 when the latter is in its highest position, as shown clearly in Figures 1 and2.

Construction-ally the present arrangement may be varied, for example, in place of the rollers, ordinary abutments or the like may be employed.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. The combination with means for transferring the matrices from the first elevator of a matrix composing and line casting ma chine to the distributor lifter bar, of a symmetrically shaped resistant one end of which contacts with the foremost of the matrix line to be transferred, to effect the erection of any matrices of the line which may hang slantwise prior to their transfer to the lifter bar and against the otherend of which the descending first elevator operates in order to return into operative position the resistant moved out of such position by the advancing line of matrices.

2. The combination with means for transferring the matrices from the first elevator of a matrix composing and line casting machine to the distributor lifter bar, of a symmetrically shaped resistant one end of which contacts with the foremost of the matrix line to be transferred, to effect the erection of any matrices of the line which may hang slantwise prior to their transfer to the lifter bar and against the other end of which the descending first elevator operates in order to return into operative position the resistant moved out of such position by the advancing line of matrices, and a spring controlled detent adapted to retain the resistant in its operative position and capable of yielding against spring action by or through movement of the resistant in either direction.

3. The combination with means for transferring the matrices from the first elevator of a matrix composing and line casting machine to the distributor lifter bar, of a symmetrically shaped resistant one end of which contacts with the foremost of the matrix line to be transferred, to eiiiect the erect-ion of any matrices of the line which may hang slantwise prior to their transfer to the lifter bar and against the other end of which the descending first elevator operates in order to return into operative position the resistant moved out of such position by the advancing line of matrices, and a spring controlled detent adapted to retain the resistant in its operative position and capable of yielding against spring action by or through move ment of the resistant in either direction, the said detent being duplicated so that by turning the resistant 180 another operative po sition is arrived at.

4. In apparatus such as described, the cornbination with a first elevator adapted to raise a line of matrices, and a lifter bar adapted to receive said line when it is moved endwise out of the raised elevator, of a doubleended resistant either end of which may alternatively extend into the path of the ascending matrices, which by contact with an obliquely hanging matrix of the line will erect said matrix. I

5. In apparatus such as described, the combin ation with a first elevator adapted to raise a line of matrices, and a lifter bar adapted to receive said line when it is moved endwise out of the raised elevator, of a doubleended resistant either end of which may alternatively extend into the path of the ascending matrices, which by contact with an obliquely hanging matrix of the line will erect said matrix, and which resistant is swung out of the aforesaid path by the end wise moving matrix line to bring the sec end end of the resistant into the downward path of the first elevator so that by the de scent of the latter the first-named end will be returned to normal position.

6. In apparatus such as described, the combination with a first elevator adapted to raise a line of matrices, and a lifter bar adapted to receive said line when it is moved endwise out of the raised elevator, f a double-ended resistant either end of which may alternatively extend into the path of the ascending matrices, which by contact with an obliquely hanging matrix of the line will erect said matrix, a shaft operatively fast to the re sistant, a disc also fast to the shaft and having diametrically opposed notches, and a spring controlled detent adapted to yieldingly engage with whichever of the notches is presented to it.

7. The combination with means for transferring the matrices from tht first elevator of a matrix composing and line casting ma chine to the distributor lifter bar, of a resistant located in the path of the foremost of the matrices to be transferred, said resistant by contact with said matrix serving to effectthe erection of any matrices of the line which may hang slantwise prior to their transfer to the lifter bar and a roller carried on the resistant adapted to bear against the ascending first elevator, so that the latter when travelling past the roller will temporarily move the stop out of its operative position in order to give a free passage to the matrices.

In testimony whereof I have affixed my signature hereto.

CARL MUEHLEISEN.
